DIAMINE DERIVATIVE, METHOD FOR PRODUCING THE SAME AND FUNGICIDE COMPRISING THE SAME AS ACTIVE INGREDIENT

摘要

PROBLEM TO BE SOLVED: To provide a fungicide exhibiting excellent control effects on Pyricularia oryzae without damaging useful crops at all. SOLUTION: The fungicide comprises a diamine derivative represented by formula (1) [wherein, R1 is a 1-6C alkyl group or the like; R2 and R7 represent each independently a hydrogen atom, a 1-6C alkyl group or the like; R3 and R4 represent each independently a hydrogen atom, a 1-6C alkyl group or the like (except when both R3 and R4 are hydrogen atoms) or a 3-6C cycloalkyl group containing bound carbon atoms; R5 and R6 represent each independently a hydrogen atom, a 1-6C alkyl group or the like; R8 represents an aryl group or the like which may be substituted; one of X1, X2 and X3 represents a sulfur atom; and all the other represent each an oxygen atom]. A method for producing the diamine derivative is provided and the fungicide comprises the compound as an active ingredient. COPYRIGHT: (C)2008,JPO&INPIT
